30 kg block that has Velatoontis sides slides across a level surface of slick ice and hits a 20 kg block that is initially at rest and has sticky Velcro on its surface. The blocks stick together and move
off in the same direction the 3.0 kg block was moving. Their speed after the collision is 10.0 m/s. How
fast was the 3.0 kg block moving before the collision?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
